The empty utility provides an interface to execute and/or interact with
|
|
processes under pseudo-terminal sessions (PTYs). This tool is definitely
|
|
useful in programming of shell scripts designed to communicate with
|
|
interactive programs like telnet, ssh, ftp, etc. In some cases empty can
|
|
be the simplest replacement for TCL/expect or other similar programming
|
|
tools because empty:
|
|
|
|
- can be easily invoked directly from shell prompt or script
|
|
- does not use TCL, Perl, PHP, Python or anything else as an underlying language
|
|
- is written entirely in C
|
|
- has small and simple source code
|
|
- can easily be ported to almost all UNIX-like systems
